[android-developers] Re: Speech recognition: prevent or automatically handle No matches found dialog
Thanks for your information. I ended up having the app sleep for several seconds and then do a finishActivity() because if nothing happened by then, some error must have occurred.

[android-developers] Re: AudioRecord creates a stereo file instead of a mono file.
I must have just gotten the parameters wrong. I can create a mono
file. But I used AudioFormat.CHANNEL_IN_MONO, not
AudioFormat.CHANNEL_CONFIGURATION_MONO.

[android-developers] Handler: UI gets updated all at once at the end
I'm using AudioRecord in a separate class, and I have it read a buffer
in a loop and callback to the main activity with the buffer.
The activity processes the buffer and calculates a number that I want
to update the UI with (I'm using animation to move a button). What
I'm finding is that first all the buffers are getting processed, and
then after that's done, the handler is apparently handling all the
messages and doing all the UI updates one after the other.
Perhaps this is working as designed because I think the handler
message processing occurs after the other work is done. If this is
true, what can I do to process a buffer and then immediately update
the UI (and do that for each buffer)?
Here's a snippet of the recording part. In the constructor, I'm
passing in a reference to the activity so I can callback to it.
Recorder(myActivity act)
{
super();
this.setFrequency(frequency);
this.setChannelConfiguration(AudioFormat.CHANNEL_IN_MONO);
this.setPaused(false);
this.act = act;
}
AudioRecord recordInstance = new AudioRecord(
MediaRecorder.AudioSource.MIC,
this.getFrequency(),
this.getChannelConfiguration(),
this.getAudioEncoding(),
bufferSize);
recordInstance.startRecording();
buffer = new byte[bufferSize];
while (this.isRecording) {
// Are we paused?
synchronized(mutex)
{
if (this.isPaused)
{
try
{
mutex.wait(250);
}
catch
(InterruptedException e)
{
throw new
IllegalStateException(Wait() interrupted!,e);
}
continue;
}
}
bufferRead =
recordInstance.read(buffer, 0, bufferSize);
if (bufferRead ==
AudioRecord.ERROR_INVALID_OPERATION)
{
throw new
IllegalStateException(read() returned
AudioRecord.ERROR_INVALID_OPERATION);
}
else if (bufferRead ==
AudioRecord.ERROR_BAD_VALUE)
{
throw new
IllegalStateException(read() returned
AudioRecord.ERROR_BAD_VALUE);
}
else if (bufferRead ==
AudioRecord.ERROR_INVALID_OPERATION)
{
throw new
IllegalStateException(read() returned
AudioRecord.ERROR_INVALID_OPERATION);
}
// Write buffer to file
try
{
fWriter.write(buffer);
}
catch (Exception e)
{
Log.d(Recorder.class.getName(),
e.getMessage());
}
payloadSize += buffer.length;
// Tell activity we have a buffer to
process
act.startLongRunningOperation();
}
Here's what I have in the activity (I instantiate Recorder in
onCreate()):
// Need handler for callbacks to the UI thread
final Handler mHandler = new Handler();
// Create runnable for posting
final Runnable mUpdateResults = new Runnable() {
public void run() {
updateResultsInUi();
}
};
protected void startLongRunningOperation()
{
// Fire off a thread to do some work that we shouldn't do
directly in the UI thread
Thread t = new Thread() {
public void run() {
mHandler.postAtFrontOfQueue(mUpdateResults);

[android-developers] How to get activity to restart every time the app is launched from the command line
Device: Nexus One
Firmware: 2.1 update 1
Platform 2.1, API: 7
I have seen it mentioned before that there's a difference between
installing an app via Eclipse and via adb, but I need more
clarification.
I have an app that starts a voice recognition activity in the main
activity's onStart() method.. I'm planning to run this app from a
Nexus One connected to a laptop via USB. I want this app to launch
perhaps 100 times, each time restarting the voice recognition
activity.
When I install the app onto the Nexus One via Eclipse, I notice this
behavior:
- when the app is launched from the command line via adb shell am
start -a android.intent.action.MAIN -n com.voice/com.voice.VoiceSearch
$1, the app runs with the voice recognition activity restarting each
time. This is the behavior I want.
- I also notice that after the app has run, I hit Home, then click on
the app from the screen, the app will be in its last state, and the
voice recognition activity will not restart. I specified
finishOnTaskLaunch=true in the manifest, so I thought the voice
recognition activity would restart.
When I package an app as per instructions and install it onto the
device via adb install, I get this behavior:
- when the app is launched from the command line, the voice
recognition app will run the first time, but subsequent launches do
not restart the voice recognition activity. The voice recognition
activity just stays in its last state. I get the following message:
Warning: Activity not started, its current task has been brought to
the front
- I also notice that after the app has run, I hit Home, then click on
the app from the screen, the app will restart the voice recognition
activity. By the way, this happens whether or not I have
finishOnTaskLaunch=true set in the manifest or not.
What do I need to do so that I can launch the app from the command
line via adb lots of times with the voice recognition activity
restarting each time?
I call this from the main activity's onStart():
private void startVoiceRecognitionActivity() {
Intent intent= new
Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, Say something!);
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
waitForResults();
}

?xml version=1.0 encoding=utf-8?

[android-developers] AudioRecord: onPeriodicNotification and onMarkerReached are not called
I've seen posts regarding problems with the AudioRecord
OnRecordPositionUpdateListener, but I haven't seen any real answers.
I'm using AudioRecord to record from the mic, and I want to get the
input from the mic periodically so I can check sound levels and update
a meter. I set up the listener like this:
private OnRecordPositionUpdateListener mRecordListener = new
AudioRecord.OnRecordPositionUpdateListener()
{
public void onPeriodicNotification(AudioRecord recorder) {
if
(recorder.getRecordingState()!=aRecorder.RECORDSTATE_STOPPED)
{
mAudioBuffer = new short[8000];
mSamplesRead = recorder.read(mAudioBuffer, 0,
8000);
if (mSamplesRead 0)
{
// do something
}
}
}
public void onMarkerReached(AudioRecord recorder)
{
if
(recorder.getRecordingState()!=aRecorder.RECORDSTATE_STOPPED)
{
mAudioBuffer = new short[8000];
mSamplesRead = recorder.read(mAudioBuffer, 0,
8000);
}
}
};
I instantiate the AudioRecord object like this:
// audioSource = MediaRecorder.AudioSource.MIC
// sampleRate = 16000
// channelConfig = AudioFormat.CHANNEL_IN_MONO
// audioFormat = AudioFormat.ENCODING_PCM_16BIT
// bufferSize = 409600
aRecorder = new AudioRecord(audioSource, sampleRate,
channelConfig,
audioFormat, bufferSize);
if (aRecorder.getState() !=
AudioRecord.STATE_INITIALIZED)
throw new Exception(AudioRecord initialization
failed);
aRecorder.setRecordPositionUpdateListener(mRecordListener);
aRecorder.setPositionNotificationPeriod(400);
aRecorder.setNotificationMarkerPosition(400);
What happens is that onMarkerReached gets called once, after the
recorder is released, so that's not very useful.
Do I need to change the marker position and notification period? Is
the listener working? Is there another way to accomplish periodically
getting the mic input?

[android-developers] AudioRecord delay in recording
I'm using a class that uses AudioRecord. RehearsalAudioRecorder recorder = new RehearsalAudioRecorder( RehearsalAudioRecorder.RECORDING_UNCOMPRESSED, MediaRecorder.AudioSource.MIC, 16000, AudioFormat.CHANNEL_IN_MONO, AudioFormat.ENCODING_PCM_16BIT); The RehearsalAudioRecorder constructor instantiates an AudioRecord: aRecorder = new AudioRecord(audioSource, sampleRate, channelConfig, audioFormat, bufferSize); I'm creating a .wav file on the SD card. I'm experiencing a 5 second delay in the recording; I play back the file, and the recording starts about 5 seconds after I started speaking. I did some measurements with System.currentTimeMillis(), and I measured the following: buffer size: 204800 bytes constructor: 17 ms write the file header: 6 ms AudioRecord.startRecording(): 483 ms AudioRecord.read(): 6268 ms There's correspondingly less delay when I use a smaller buffer: buffer size: 81920 bytes constructor: 16 ms write the file header: 5 ms AudioRecord.startRecording(): 486 ms AudioRecord.read(): 2427 ms Does anyone have any suggestions as to how to reduce the delay? It's still unacceptable to have a few seconds delay. -- You received this message because you are subscribed to the Google Groups Android Developers group.

I write a .wav file to the SD card. I specified mono, and I checked
that CHANNEL_CONFIGURATION_MONO is indeed set in the AudioRecord
object. But when I try to play the file, it's treated as if it's
stereo, and voices sound like chipmunks. Apparently the header
information is wrong. For instance, I open the .wav file in Audacity,
and Audacity says it's stereo.
Is this a bug? What can I do?

[android-developers] RecognizerIntent speech prompt not getting focus upon activity relaunch
I used VoiceRecognition.java as a starting point for my app. But
instead of having a button that when clicked calls
startVoiceRecognitionActivity() to fire a RecognizerIntent to start a
voice recognition activity, I called startVoiceRecognitionActivity
directly from onCreate().
I need to launch the app from a pc via adb shell am start -a
android.intent.action.MAIN -n my app $1, and I need to launch the
app multiple times. If the activity is already running, and I use the
adb command to launch the app, the view displays, but the speech
prompt does not display.
I noticed an issue related to this has been raised, but I don't know
if it's been resolved.
http://code.google.com/p/android/issues/detail?id=2914
So is it a focus issue? The RecognizerIntent is getting fired, and
it's just not getting the focus? What do I need to do to force it to
have the focus?
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Begin voice recognition
startVoiceRecognitionActivity();
// Inflate our UI from its XML layout description.
setContentView(R.layout.voice_recognition);

mList = (ListView) findViewById(R.id.list);
}

looking for?);
